style="text-indent:25px">對熱軋輥來說，輥面不允許出現(xiàn)裂紋，表面裂紋缺陷容易造成應(yīng)力集中，加速擴(kuò)展而使軋輥失效。熱疲勞裂紋主要起因于周期**變熱應(yīng)力，嚴(yán)重情況下，裂紋擴(kuò)展可能造成輥面剝落，甚至斷輥。冷軋輥主要失效形式包括劃傷、粘輥和剝落等。冷軋輥輥身表面應(yīng)有高而均勻的硬度，其優(yōu)劣表現(xiàn)在輥身工作層的耐磨性，即耐粗糙性。熱軋工作輥進(jìn)行的熱處理一般有鍛后熱處理和調(diào)質(zhì)。鍛后熱處理的主要目的是消除鍛后應(yīng)力，細(xì)化晶粒，改善切削性能。鍛后熱處理還有擴(kuò)氫作用。</p><p style="text-indent:25px">鑄鋼軋輥 ?：一般按含碳量分類：含碳極高（1.4～2.4%）的過共析鋼軋輥，俗稱半鋼軋輥，高碳的半鋼軋輥實(shí)際已伸入鑄鐵領(lǐng)域；高碳過共析鋼軋輥還有一類為石墨鋼軋輥，其石墨是通過孕育和熱處理獲得的。：鍛鋼軋輥 ?一般按用途分類。?其他采用特殊加工工藝的以外，都直接以材質(zhì)稱呼。如用電渣重熔鑄造坯料鍛壓的軋輥稱為電渣重熔鍛壓軋輥。軋輥的損壞原因：軋機(jī)部件中軋輥的工作條件比較為復(fù)雜。軋輥在制造和使用前的準(zhǔn)備工序中會產(chǎn)生殘余應(yīng)力和熱應(yīng)力。使用時(shí)又進(jìn)一步受到了各種周期應(yīng)力的作用，包括有彎曲、扭轉(zhuǎn)、剪力、接觸應(yīng)力和熱應(yīng)力等。這些應(yīng)力沿輥身的分布是不均勻的、不斷變化的，其原因不僅有設(shè)計(jì)因素。軋輥按制造方法又可分為整體鑄造軋輥和復(fù)合鑄造軋輥兩類。</p><div

⑷鍛造白口鑄鐵軋輥。工藝方法：整體軋輥、冶金復(fù)合軋輥和組合軋輥。1、整體軋輥是相對于復(fù)合軋輥而言的，整體軋輥的輥身外層與心部以及輥頸采用單一材質(zhì)鑄造或鍛造而成，輥身外層和輥頸不同的組織、性能通過鑄造或鍛造工藝以及熱處理工藝過程來控制和調(diào)整。鍛造軋輥和靜態(tài)鑄造的軋輥均屬于整體軋輥。整體軋輥分為整體鑄造和整體鍛造軋輥兩種；?特殊軋輥：它用于鋼管軋機(jī)、車輪軋機(jī)、鋼球軋機(jī)及穿孔機(jī)等**軋機(jī)上。上海軋輥生產(chǎn)廠家排行榜</p><p
